Description

Quantum walks are powerful tools not only to construct the quantum speedup algorithms but also to describe specific models in physical processes. Furthermore, the discrete-time quantum walk (DTQW) has been experimentally realized in various setups. We show the limit distribution of the DTQW with the periodic position measurement under the time scale transformation and its connected to some physical-related models.
